Title: Improved Device for Indicating the Condition of the Electric Circuit Controlling the Air Brake Valves on a Train.
Filed: 1903-01-12
Granted: 1903-11-12
Abstract: 778. Siemens Bros. & Co., [Siemens & Halske Akt.-Ges.]. Jan. 12. Stopping trains.-In a system of air brakes in which the several valves throughout the train are controlled by opening or closing an electric circuit, the main air pipe is provided with a special inlet or outlet valve to indicate any fault in the circuit controlling the brake valves. The indicating-valve is controlled by a continuous electric current, so that the air is released and the brakes are applied if there is any defect in the circuit. Fig. 1 shows an arrangement in which an independent source d of electricity is used in the circuit a, b containing a solenoid g for operating the valve i. A conductor c is connected to the conductor a by the switches e controlling the electrically - operated air - brake valves f in the several carriages. If the current in the circuit a, b fails or is disturbed, the solenoid g fails to keep closed the valve i, so that the air in the pipe h is released and applies the brakes, and indicates to the driver that the brake device is out of order. In the arrangement shown in Fig. 2, a second solenoid i around the core u is connected by a wire c to the driver's switch p. When an emergency switch d in the train is closed, the current flows from the lead a through the electricallyoperated valve e to the earth, and the brakes are applied. If the current fails in the lead a, the core u is released by the solenoid g, and the valve v opens so as to release air from or admit it to the brake pipe x. To apply the brakes, the driver moves the switch handle to the position II, cutting oat the current from the lead a and supplying it to the lead b, so that the valves e, v are all opened. To take off the brakes, the switch handle is moved to position III, and the current flows through the valves f and solenoid coil i to earth, the core u closing the valve v.

Title: Improvements in the Process of Converting or Bessemerizing Matte.
Inventor: GARRETSON OLIVER STEPHENS
Filed: 1903-05-18
Granted: 1904-03-24
Abstract: 11,303. Garretson, O. S. May 18. Blast furnaces; converter furnaces.-Relates to the process of converting or Bessemerizing matte in a blast furnace under a column of ore or flux. The rich slag, formed in the primary furnace, is run, preferably through a settling-well, into a secondary furnace or forehearth where it is treated with sulphur-bearing material, so as to produce a low-grade matte and clean slag. The matte from the well and the secondary furnace may be returned to the primary furnace, where it is converted into metal or rich matte. Preferably, the furnaces are of the water-jacketed blast-furnace type, but the secondary furnace may be a reverberatory. In the primary furnace, ore may be melted while the matte is being converted, either with the aid of two rows of tuyÞres, or with a single row of tuyÞres below the level of the molten matte. In that case, the excess of air, after it is heated by converting the matte, is utilized for smelting. Fig. 1 shows an arrangement of two blast furnaces A, E with an intermediate settling- well D. The tap holes b, d<1>, g are provided for matte or metal, and tap holes c, d, g<1> for slag. The latter tap holes may be adjustable in height. The primary furnace has two rows of tuyÞres, and the secondary only one. The hearth of the secondary furnace may be divided by a dam, consisting of water-circulating tubes h, to retain some matte on one side.

Title: Improvements in Breech-loading Ordnance.
Inventor: TASKER VERNON COMPTON
Filed: 1903-06-11
Granted: 1903-10-08
Abstract: 13,137. Tasker, V. C. June 11. Ordnance breech mechanism. - Relates to improvements upon the invention described in Specification No. 21,276, A.D. 1902. Fig. 1 shows a horizontal section with the breech - screw locked, Fig. 2 an end view, Fig. 4 a vertical section with the breech-screw unlccked, and Fig. 12 an inside view of the breech-screw carrier. The breech-screw carrier C has an inwardly-projecting spindle C', C<2> having its exterior, which receives the breech-screw B, eccentric to the gun axis, and its interior, which receives the casing K of the firing-mechanism, concentric to the gun axis. When the lever L, which is pivoted to the carrier C, is swung outwards, it acts through the bevel gearing B<6> and rotates the breech-screw into unlocked position, bringing the eccentric opening B<3> in its face out of line with the hammer D<1> and the cartridge primer, and thus making it impossible to discharge the gun until the breechscrew is again in locked position. When the breech-screw is unlocked, a projecting piece B<2> upon it comes against a stop C'‹ on the carrier C and thus prevents further rotation, while backward movement is prevented by a spring catch N, which is pivoted at C<13> to the carrier and acts as soon as the carrier begins to move away from the gun breech. A modified spring catch is arranged to act as a strut against the end of the breechscrew to prevent it from rotating. A pawl Z, having a heavy part Z<2> and a spring Z<4>, locks the operating-lever L to the carrier, the heavy part acting at the instant the recoil is checked, and thus preventing the lever L from accidentally swinging open. The firing-mechanism in the casing K is described in the above-quoted Specification. The arm P' on the firing-spindle P is operated by a pallet S<1>, carried on a shaft S, which is rotated by the hinged lever U. The casing K of the firing- mechanism connects the breech-screw B to the carrier C by a bayonet joint, and is itself prevented from rotating into unlocked position by the spring pin R. This arrangement enables the breech mechanism to be taken to pieces by hand.

Granted: 1904-07-07
Abstract: 18,834. Threlfall, R. Sept. 1. Pressure gauges. -In a differential manometer, the pressures act on liquid surfaces contained in a U-tube or in connected bottles, the levels being determined by needle points and the difference in levels being read on an external vernier. The two bottles 1, Fig. 1, are connected by a siphon tube 2 provided with a tap 3, and the needle points are adjusted to the surfaces of the liquid by means of micrometer screws 12 which depress the indicating rods 7 against the action of the spring 11. The points are adjusted to the surface levels when the tubes 4, 5 are open to the atmosphere, and again when they are connected to the pressures the difference between which is required. The movements of the micrometer screws 12, which are read off on verniers, determine the equivalent height of the liquid column. As a modification, each rod 7 may be provided with a horizontal jaw 10, the distance they open or close giving a measure of the pressure difference; or the threads of the screws 12 may be cut accurately so that the amount of turning of each head gives the necessary indication.
